Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method for non-exclusive multiplexing of at least one active control channel comprising: preparing the at least one active control channel for transmission in a next frame using a transmitter data processor, wherein the at least one active control channel is prepared for transmission using a non-exclusive multiplexing constellation; assessing channel robustness of the at least one active control channel based on a channel robustness threshold; and if the channel robustness threshold is not met, performing constellation control or power control on the non-exclusive multiplexing constellation of the at least one active control channel prior to transmitting the at least one active control channel; or if the channel robustness threshold is met, transmitting the at least one active control channel using a transmitter.
A method for managing multiple active control channels concurrently involves preparing these channels for transmission in the next frame using a data processor within the transmitter. Each channel is prepared using a non-exclusive multiplexing constellation. The method then assesses the channel robustness of each active control channel against a defined threshold. If a channel's robustness is below the threshold, constellation control (adjusting the signal pattern) or power control (adjusting the signal strength) is performed on the channel's non-exclusive multiplexing constellation before transmission. If the channel robustness is above the threshold, the active control channel is transmitted directly using the transmitter.
2. The method of claim 1 wherein the performing constellation control step comprises eliminating a first constellation point in the non-exclusive multiplexing constellation.
The method described previously, where multiple active control channels are managed concurrently, refines the constellation control step by eliminating one specific constellation point from the non-exclusive multiplexing constellation of a channel when its robustness is below the required threshold. This removal is done to improve the reliability of the transmitted signal in adverse channel conditions.
3. The method of claim 2 wherein the first constellation point has a minimum distance from a second constellation point in the non-exclusive multiplexing constellation.
In the method of managing multiple active control channels, the constellation control process refines the selection of the constellation point to be eliminated. Specifically, the constellation point removed is the one with the minimum distance from another constellation point within the non-exclusive multiplexing constellation. This minimizes the risk of incorrect decoding if the receiver incorrectly interprets the altered signal.
4. The method of claim 3 wherein the minimum distance is a Hamming distance.
In the method of managing multiple active control channels, the "minimum distance" used to select a constellation point for removal during constellation control is specifically defined as the Hamming distance. This means the constellation point that differs by the fewest bits from another point is the one removed, providing increased error resilience.
5. The method of claim 1 wherein the constellation control includes a cyclic redundancy check (CRC) code.
The constellation control applied in the method for managing multiple active control channels includes adding a cyclic redundancy check (CRC) code. This CRC code allows the receiver to verify the integrity of the received control channel data and detect errors that may have occurred during transmission, even after constellation control.
6. The method of claim 1 wherein the channel robustness threshold is based on one of the following metrics: signal-to-noise ratio (SNR), fade rate, bit error rate or frame error rate.
In the method of managing multiple active control channels, the channel robustness threshold is determined based on one or more metrics: signal-to-noise ratio (SNR), fade rate (how quickly the signal strength changes), bit error rate (BER), or frame error rate (FER). If any of these metrics indicate poor channel quality, the method applies constellation or power control.
7. The method of claim 1 further comprising transmitting the at least one active control channel using one of time-division multiplexing (TDM), frequency-division multiplexing (FDM), code-division multiplexing (CDM) or a combination thereof.
